With the rapid advancement of automotive lighting technology, car LED light sources have become the preferred choice for modern drivers and manufacturers. From turn signals to brake lights, LED bulbs offer superior brightness, energy efficiency, and durability compared with traditional halogen lamps.
Among the many socket types in the automotive sector, the 1156 (BA15S) and 1157 (BAY15D) bulbs are two of the most popular standards. They are widely used in automotive tail lights, brake lights, signal lamps, and reverse lights—and at Zhishan, we specialize in providing high-quality LED replacements designed to meet global standards and customer expectations.
The difference between the 1156 and 1157 LED bulbs mainly lies in their structure and function:
● 1156 LED Bulb (Single Contact BA15S) – A single-function bulb commonly used for turn signals, backup lights, and daytime running lights.
● 1157 LED Bulb (Dual Contact BAY15D) – A dual-function bulb that serves both brake and tail light roles in one unit.
Though visually similar, these bulbs differ in pin alignment, contact configuration, and circuit design. Selecting the right model ensures reliable lighting performance and avoids compatibility issues.
At Zhishan, our engineering team produces both 1156 and 1157 LED series that feature precise socket fit, consistent brightness, and advanced circuit protection.
